This invention relates to improvements in seals, and more particularlyseals for securing together the overlapped ends of metal straps or bandssuch as are used in the bind- .ing of boxes, bales, packages and thelike.

The present seal is an improvement over vthe seal disclosed in theFloraPatent No. 1,252,680, granted January 8,1918.

.An object of my invention is the provv vision of an improved Seal ofthe type specified, which is so formed as to greatly increase itstensile strength.- I have accomplished this object bymaking certainadditional deformations conjointly in the sleeve 16 amd in theoverlapped ends, and in such positions with respect tothe marginaldeformations that the parts are caused to firmly interlock and preventrelative longitudinal movement.

In the formation of my improved seal 'I make marginal deformations inthe parts to be sealed together and simultaneously form interlockingshoulders on the seal by making crosswise deformations therein, theshoulders being forced up between the depressions by the marginaldeforming pressure. I may further strengthen the seal by making alongitudinal depression in the top of the seal between the crosswisedepressions.

In theaccompanying drawings illustrating one specific embodiment of myinvention,

Figure 1 is a perspective view of an improved seal made in accordancewith my invention.; a i

Figure 2 is a plan view of the seal shown inFigurel; 1. p

Figure 3 i's a section takeii on the line ofF1gure2;

Figure 4 is a section taken on the line 4-4 of Figure 2; and

Figure 5 is a bottom plan of the seal shown in Figure 2. f y

The seal, indicated as a whole by numeral 6, comprises the overla pedstrap ends 4 and 5 on which is fitted as eeve 7 vhaving return bentanges 8 and 9 thereon, which initially extend inwardly in aplane-parallel with the top of the sleeve but which are forced into asubstantially vertical position at.v the central portion of the sealwhen the marginal.

deformations 11 are made in the sleeve. The

strap ends 4 and 5 are preferably providedwith interlocking lraisedportions 12 and 13 illustrated in'Figures 4 and 5, which portions aid inrestraining the strap ends from relative longitudinal movement while theseal is being formed. They also serve-this lfunction to some extentafter the completion of the seal owingto the fact that the end 14 of thesleeve, together with the iange 8, securely embraces the portions 12 and13 and holds y them in their initial position.-

The deformations 11 made in the margins of the seal cause the edges 17and 18 of the strap to bend downwardly as' shown in Figure 3, 'and forcethe intermediate portions 21 and 22 upwardly into shoulders and withinthe shoulders 23 of the sleeve. Between the shoulders 21, 22 and 23 thesleeve and n the strappingare conjointly deformed, form- 70 ing4 thedepression 25 in the sleeve and depressions 26 and 27. in the strapping.These latter deformationsl produce the downwardly extending ridges 28and 29 on the strapping,- which securely hold the central portions ofthe anges 8 and 9 in their substantially vertical position and verysubstantially strengthens the tensional resistance of the seal.

At opposite sides of the marginal deformations 11 and at opposite endsof the longitudinal ydeformation 25 I form crosswise deformations 32Aand 33 which, together with the longitudinal deformation 25 produce anH-'shaped depression. Between the parallel deformations v32 and 33 themarginal vdeformations 11 are formed, causing the elements of the sealto firmly interlock inthe manner shown in Figure 3. The crosswisedeformations 32 and 33 also produce interlocking shoulders 38, 39 and 40longitudi- 90 i nally spaced from the crosswise deformations -whichmaterially strengthen the seal. `Almore particularly because of thespecific relative positions of the various deformations. It has beenproven from extensive experiment that a seal made in accordance withthis invention has a tensional strength equal to that of any otherportion of the band or strap.

K thou h I have shown and described only one specic embodiment of myinvention, it will be understood by those skilled in the art thatmodifications may be devised for accomplishing the objects of thisinvention without departing from the spirit thereof, and I desire toavail myself of such modifications as come within the scope of theappended claims.
